* include/hbapierr.h
  * src/harbour.def
  * src/rtl/errapi.c
    + added new C function:
         void hb_errReinit( PHB_ITEM pError );
      it allows to replace default error object with user custom one which
      support :Init() method

  * contrib/xhb/xhb.hbp
  + contrib/xhb/xhb.h
  + contrib/xhb/xhberror.prg
    + added code which extends Harbour error objects adding functionality
      known from xHarbour:
         oError:ProcName
         oError:ProcLine
         oError:ProcModule
      Above instance variables are initialized automatically when error
      object is created.
      To enable this functionality it's enough to add to PRG code:
         REQUEST xhb_ErrorNew

  * contrib/xhb/xhberr.prg
    * use error object :Proc*() methods if they are available
    - removed PRG version of xhb_ErrorNew()

  * contrib/xhb/xhbmemo.prg
  * contrib/xhb/xhbtedit.prg
    ! use xhb_ErrorNew() instead of ErrorNew() which does not support
      any parameters

  * include/hbapicls.h
